To afll'wwm t may concern:

Beit known that I, JACOB E. Lxnnnan'r, a citizen of the United States,residing at Toluca, in the county of Los Angeles and State ofCalifornia, have invented new and usefuY lImprovements in a Combined HayBuck and Stacker, of which the following is a specification.

The object of my invention is to provide a device having means for itsself repulsion which will readily buck hay in itslbose-positionen theground, carrying it to the desired location and there stack the same.

I accomplish this object b means of the device described herein and ilustrated in the accompanying drawings in Which--v Figure 1-is Aa sideelevation of my improved buck and stacker, partly broken away, thedotted iines showing it in ,ositionV for bucking the hay to be stackedan in full lines in its position while being moved. Fig. 2-is a sideelevation thereof, the parts being shown in its vertical position whichit assumes when unloading the ha onto the stack. Fig. 3- is a planthereof, broken away in arts.

My device, being self propelle is adapted to be run into the field, andgather the hay to be stacked from cocks, rows or piles and transport thesame to the place Where it is to be stacked, and stack it.

In the drawings 1 is the frame or Vbed of th device upon which thee 'ne2 is mounted, upon the crank shaft of which is keyed a sprocket 3. Forthe pur oses of my invention I have shown a gaso ene en 'ne of ordinaryconstruction adapted for p acement on a frame' and to transmit lmotionto the rear axle through a sprocket 4 keyed to the driving axle 5, asprocket chain 6 transmitting motion from the front sprocket on thecrank shaft of the engine tothe rear sprovziketV on its driving axle.The device is steered by means of the steering wheel 7 mounted on thesteering coiumn 8. Keyed to the lower end of the steering rkcolumn is asprocket 9, a sprocket chain 10 extends forwardly rand around a sprocket11 on the guide wheel V12. This will be seen, is manipulated by thesteering Vwheel 7. Keyed to the driving shaft 5 are the dri ving wheels13. Now, when it is desired to convert the device into a self propelledvehicle the hand lever 14 is thrown to the left. This will carry with itthe clutch 15, which has a longitudinal movement on the crank shaft (butis non-rotative thereon) b y means lof the engaging yoke 16 mounted uponthe hand lever 14. This will throw the ciutch 15 into locked engagementwith clutch 17 and impart movement to sprocket chain 6 and thereby movethe device. A reverse movement isimparted to the sprocket wheel 3 andcauses Ythe device to move backwardly by throwing the hand lever 14 tothe right to the limit of its stroke by means of the mechanisnicontained in the casing 18. A This revers'- ing mechanism, for reversemovement, is not shown as it is ofthe ordinary construction andembodies-no novelty. Movement being imparted tothe device as shown thestacker is guided by the steering wheel 7 to the position desired, thegathering fork 19 being dropped for o erationv into the dotted positionshown in ig.a 1. The forks are thrown into this dropped or operativeposition by moving forwardlythe segment lever 20 into the dottedposition shown in Fig. 1, the

swinging yoke 22 having a pivotal movement Y on and supported by thebolt 21 on the main frame.

On the fork sup orting frame 25 I have `placed lugs 38 which when theframe is in its dropped position will drop in front of the axle andcontact therewith and hold the fork in its forward position when inoperation in bucking the hay to be loaded.

The outwardly projecting fork tines 19 are mounted upon the projectingend of the fork carrying frame 25. This ame has a swinging movement onthe wrist pin 26 on the rev- Yoluhie shaft 23, operating in theelongated sist 26a. On the rearend of the frame is mounted the block 27through which the rope 28 renders. This rope is securely fixed at oneend to the revcluble drum 29. This .drum is revolubly mounted inbearings in the frame and has on the' outer peri hery thereof spur gear36 which meshes Ywit a pinion 37 on the crank shaft. its outer end tothe hook 3G secured to the free end of theswinging yoke 22. Extendingdownwardly from the yoke 22 to the free end of the fork frame 25 are theguy ro'ds 31 workably connecting the swin ing yoke 22 with the forwardend of the ork carrying frame 25. Now when it is desired to throw thefork from its depressed position shown in dotted lines in Fi 1 into ltselevated position as shown in Fgig. 2 the lever 19 is thrown to the leftcarrying the yoke on the other end thereof Voutwardly and moving theclutch32 into engagement with clutch 33 rigidly se- -cured to the ropewinding drum 29. This ICQ IOS

IIQ

will cause the rotation of the drum and wind up the rope 2S throwing thefork and its sup porting frame into its elevated or unloading positionshown in. Fig. 2. The clutch 32 has a longitudinal movement on the crankshaft, but is nou-rotative thereon and the rope winding drum 2%) isthrown into or out of engagement with the enginc by the operation of thelever It). When power is applied to the winding drum andthe rope 28rapidly wound thereon the forks and the outer end of the supportingframe will move up rapidly until the lower end of the fork supportingframe contacts with the ground when it will be brought to a more or lessabrupt stop, jarring and throwing the hay backwardly and, off of theupwardly projecting tines 34 which are then in a nearly horizontalposition, the outwardly projecting ends being slightly depressed. Thisposition will always insure the removal of the hay from the fork andtoss the same outwardly and backwardly therefrom into space permittingit to drop upon thc stack being formed thereunder.

Having described my invention what I claim as new and desire to secureby Letters Patent is:-

1. In a device of the character described, the combination of anoscillatory fork-carrying frame, hoisting mechanism, and means forfulcruming the fork-carrying frame at an intermediate point during aportion of its os cillation and for changing the fulcrum or pivotalpoint to a point on the ground to in-- crease the throw or movementthereof.

'.Z. 1n a device of the character described, the combination with avehicle, of a fork carrying frame having sliding pivotal connection withthe vehicle, and means for throwing it upwardly into a position so thatone end rests upon thc ground upon which end it is swung by the saidlifting means.

3. In a device of the character herein dcseribed, the combination with avehicle frame, of a fork carrying frame having elongated slots, a fork,a revoluble shaft having cranks, said cranks having wrist pins whichenter said slots, a winding drum, a yoke connected to the fork carryingframe, means connecting the winding drum and yoke whereby the forkcarrying frame is tilted, the wrist pins forming a pivot upon which thefork carrying frame swings, and means for elevating the fork carryinframel on said wrist pins until one end of t e frame rests upon theground, after which the frame is further swung upon the ground to an aproximately vertical position, whereby t c hay is automatically thrownfrom the fork when raised to said vertical position.

4. In a device of the character herein described, a vehicle, a forkcarrying frame pivotally connected therewith, means to elevate or lowerthe front end of the fork carrying frame, said means comprising arevoluble shaft mounted on the vehicle, this shaft hav ing a crank bywhich it has sliding pivotal connection with the fork carrying frame,and an adjustable lever secured to the shaft for regulating the same.

5. The combination with a vehicle frame, of a fork carrying framesupported by the vehicle frame, a yoke pivotally connected to the forkcarrying frame, a conl'iection extending from the yoke to the forkcarrying frame, means carried by the vehicle for tiltingr thc forkcarrying frame. in one operative position, and independent means forswinging the fork carrying tioned. means whereby to throw it into an.ap-- proximately vertical position.

6. The combination of a self propelled ve hicle, steering mechanism, afork carrying frame carried by the vehicle, a revoluble shaft havingcranks thereon, to which cranks the fork carrying frame is pivotalfyconnect ed, means on the shaft for turning it whereby to tilt the forkcarrying frame into one opera tive position, a pivotaliy mounted yoke,rods extending from the yoke to the fork carrying frame, a sheavecarried by the vehicle, a flexible device extending from the yoke aroundthe sheaves, and a drum operating by the propelling means of the vehichto which one end of the iiexiblc connection is secured, and means forcausing the drum to wind the flexible connection thereon, whereby toraise the fork carrying frame to an al'iproximately vertical position.
